Specification of Letters Patent.

Patented June 28, 1910.

Application filed June 1, 1909. Serial No. 499,532.

T all whom it may concern:

Be it known that we, JACOB T. OLIPHANT and OLLIE RING, citizens of theUnited States, residing at Farmersburg, in the county of Sullivan andState of Indiana, have invented certain new and useful Improvements inTedder Attachments for Harvesters, of which the following is aspecification.

Our invention relates to certain new and useful improvements in tedderattachments for harvesters, and the object of our invention is toprovide a tedder attachment which is capable of being attached to anyharvester, and which can be readily detached therefrom, the attachmentbeing so constructed that while it can perform all the functionsnecessary, it in no way interferes with the action of the harvester, andwhich does not require any adjustment of the parts of the harvester whenbeing attached thereto or detached therefrom.

\Yith these and other objects in view our invention consists in certainconstructions, combinations and arrangements of parts, the preferredform of which will be first de scribed in connection with theaccompanying drawings andthen the invention pointed out in the appendedclaims.

Referring to the drawings wherein the same part is designated by thesame reference numeral wherever it occurs Figure l is a top plan view ofa portion of the mowing machine with our invention applied thereto; Fig.2 is a side elevation of Fig. 1 and Fig. 3 is a detailed perspectiveview of the device for fastening the attachment to the seat support.

1 designates the axle, 2, 2 the wheels, 3 the pole, l the seat and 5 theseat support secured in position by any suitable means as by the belts4.0 of a mowing machine of any ordinary or desired construction.

In the form of invention shown, and as best appears from Fig. 3, theseat support 5 is secured to the central portion of the axle l, and thisseat support is of the ordinary fiat metal plate construction.

The tedder attachment comprises a U- shaped frame 6 in the ends of whichis journaled the crank shaft 7 having a plurality of cranks for thetedder forks 8.

9, 9 are a pair of braces extending from the back portion of the U frame6, said bars being preferably formed integral with each other andconnected together by the U shaped section 10, the portion 11 of whichis rounded and journaled in a journal box 12, from which there extendsout the yoke 13 having centrally located therein the setscrew 14. Thisyoke is adapted to surround the seat support 5. We preferably insert inthe yoke between it and the seat support a bearing plate 4L1 againstwhich the screw is adapted to bear so that by turning up the set screwclamps the journal box 12 tightly against the same.

15, 15 are a pair of bars extending back from the bars 9, and their ends16 are provided with journals for the crank shaft 7 whereby additionalbearings for this shaft are provided.

17 is a cross brace extending between the braces 9, 9.

18, 18 are a pair of links provided at one end with an eye 19, and atthe other end with an eye 20, the eye 19 being adapted to slip over theend of the shaft 7 and the eye 20 over the ends of the axle 1, thebraces being held in position by means of the cotter pins 21. It will benoted that the journal block 11 is supported in the plane of the axis 1,and that therefore the tedder frame may be raised and turned about theaxle 1 as a center.

As a means for raising the tedder frame we have illustrated the lever22, pivoted on the pole 3, said lever being provided with the ordinarylatch 23 engaging a sector 2&.

25 are a pair of links extending from the U frame 6 to the lever 22.

From this construction it will be seen that by moving the lever 22forward the tedder frame will be raised.

For the sake of illustration we have shown the tedder forks 8 as beingformed of a bar 26 provided on its lower side with the eye 27 throughwhich one of the cranks of the shaft '7 passes, said bar at its upperend being connected back to the U frame by means of the rods 28, wherebyupon rotation of the crank shaft proper motion of the tedder forks willbe given.

29 are the tedder forks which are shown as pivoted at 30 to the lowerend of the bar 26.

31 is a coil spring connected at one end to the bar 26 and at the otherend, by means of a connecting rod 32, to an arm 33 on the fork, so thatshould the forks come in contact with a stone or other obstacle or stickinto the ground they will yield instead of being broken.

Mounted on the shaft 1 adjacent one end thereof is a sprocket wheel 3 Lconnected by a sprocket chain to a sprocket wheel 36 on the crank shaft7, whereby the crank shaft is driven from the axle 1.

It is believed that the operation of our device will be obvious from theforegoing description.

WVe realize that considerable variation is possible in the details ofconstruction and arrangement of parts without departing from the spiritof our invention, and we therefore do not intend to limit ourselves tothe specific form shown and described.

Having thus described our invention what we claim as new and desire tosecure by Letters Patent is l. The combination with a harvester havingan axle and a seat support mounted on the axle, of a tedder attachmenthaving a frame, a boxing in which the forward portion of the frame isjournaled, a clamp carried by the boxing and engaging the seat support,a lever carried by the harvester and rods connecting the lever andtedder frame whereby the same may be raised and lowered.

2. A tedder attachment forharvesters secured thereto by bars, a boxingin which said journal is mounted, and means carried by the boxingwhereby the same is adapted to be clamped to the seat support of aharvester.

3. The combination with a harvester having an axle and a seat supportmounted on the axle, of a tedder attachment having a frame, a crankshaft mounted in the frame, tedder forks mounted on the crankshaft, aboxing in which the forward portion of the frame is journaled, a clampcarried by the boxing engaging the seat support,v a pair of rods havingan eye in each end and connecting the ends of the crank shaft with theends ofthe axle, a lever carried by the harvester and rods connectingthe lever and tedder frame whereby the same may be raised and lowered.

In testimony whereof we aflix our signatures in presence of twowitnesses.
